| IRS990ScheduleD/SupplementalInformationDetail/ExplanationTxt | 0 | Income TaxesFinancial statement presentation follows the recommendations of ASC 740, Income Taxes. Under ASC 740, LPIE is required to report information regarding its exposure to various tax positions taken by LPIE and requires a two-step process that separates recognition from measurement. The first step is determining whether a tax position has met the recognition threshold; the second step is measuring a tax position that meets the recognition threshold. Management believes that LPIE has adequately addressed all tax positions and that there are no unrecorded tax liabilities as of June 30, 2018.LPIE has received notification from the Internal Revenue Service and the State of California that it qualifies for tax-exempt status under Section 501(c)(3) of the Internal Revenue Code and Section 23701d of the California Revenue and Taxation Code. The exemptions are subject to periodic review by the federal and state taxing authorities and management believes that LPIE continues to satisfy all federal and state statutes in order to qualify for continued tax exemption status. |
